[QUOTE="MattinMO, post: 8703763, member: 674315"] I’m not reading all this hoopla above but do the big three and see what happens, if Voltage is still dropping add a 2nd battery. Johnathan Patrick of brand x and formerly ces alternators wrote this up not too long ago: Reasons why you NEED a big 3 BEFORE installing an HO alternator EVEN IF YOU DONT HAVE THE SYSTEM INSTALLED YET! There are numerous reasons the alternator can generate hundreds of amps of current over your factory fuse rating. This is especially common in late model Honda, Hyundai, Toyota, and kias. This can blow the factory fuse on the top of the battery, this isn’t a cheap part, sometimes costing 100+$ from the dealer. *Autozone and advance generally don’t carry these parts.* you can damage your computer as well from the voltage spike associated with the fuse blowing, the regulator in the alternator, the rectifier in the alternator as well. Reason 1: if your battery ever gets low enough from starting or sitting long enough the alternator is not smart enough to *slow charge* your batteries, due to this you can blow the fusing / mega fuse/ breaker associated with the factory electronics / fuse terminal on the battery. Reason 2: if you jump someone’s car, or receive a jump you can damage all of the same components referred to above. Reason 3: you didn’t follow your other directions with the install and your batteries were not charged before firing it up. Reason 4: you don’t need a reason 4, be smart. Install your alternator according to directions... you’ll have a way better time with it I promise. [/QUOTE]
